[JENKINS-35379] gerrit-trigger no longer triggers build

After updating gerrit-trigger from 2.20.0 to 2.21.0 jobs no longer get triggered when a change gets pushed to Gerrit. Manually trying to trigger a Gerrit event manually doesn't work either. Sometimes it reports that a job was triggered (but that job never appears in the build queue), sometimes it claims that no job was triggered.

First I thought it might be caused by our Gerrit version, so I upgraded that from 2.10.5 to 2.12.2, but that didn't help.

It worked nicely before the upgrade of gerrit-trigger, and started to work again after I downgraded to 2.20.0.
